I'm also with the PMS|H2O clan I'm the co community manager for the L4D2 division. I highly recommend them if you are thinking of joining a clan. We have all platforms and a division for all the big games. I have met some brilliant people being there so I am just sharing my experience

Don't play loads on there, just compare trophies to see what I play,though there's a couple from call of duty from when I gave it a try- I haven't played since but will play if you want (just expect me to suck REALLY badly XD).

Also, if not too much trouble, could you send a message to let me know who you are (or jsut that you're from this site)

I plan to get: Bioshock 1 and 2, plus Infinite (when released), Lollipop Chainsaw (when released), No More Heroes: Heroes' Paradise and Rayman Origins. I don't really play online games at all ever... xP
